And that’s not all undershirts are capable of. Undershirts are functional and serve a purpose, but nowadays, they can also steal the show in your daily look.

We've got you covered whether you're searching for a classic cotton undershirt or a stylish v-neck. Something that will keep you warm all winter long.

Why Are Undershirts Important?

Undershirts serve a couple of very important purposes. However, they are often overlooked when stocking a wardrobe because they still have an outdated image in the world of fashion.

The basic purpose of an undershirt is to absorb your sweat. This is so your top layers can maintain a pristine appearance for years. Undershirts are a defensive layer between the body’s natural production of sweat and oils and your more expensive shirts. They're easier to wash and won't cause sweat/deodorant stains on your more fashionable clothing.

Another purpose an undershirt serves is to add another layer of insulation and warmth to an outfit. Long-sleeve undershirts are perfectly designed to fit under a dress shirt or business suit. It allows you to still look chic even in the dead of winter. 

The variety of undershirts has multiplied over the years. This means you can style your undershirt to match any outfit you choose and not think of it as a basic utilitarian piece of clothing. 

Types of Men’s Undershirts

It’s a widespread belief that showing your undershirt is seen as a fashion faux pas. If we're talking about old, sweat-stained, worn-out white tees, then yes, keep them to yourself. But we have so many styles of undershirts to choose from that those unflattering white undershirts can stay in the closet.

The simple and understated undershirt has blurred the lines between fashion and function. It’s made its way to centerstage, with actors in Hollywood blockbusters stealing the show wearing nothing but a low-key undershirt. 

With so many different types of undershirts out there, you’ll surely find one that suits your style perfectly.

Crewneck T-Shirts

Crewneck T-shirts have been around for decades and are the original undershirt. Their popularity took a turn in the 1950s, and they started to be seen as the ultimate sign of cool. 

This undershirt can be as versatile as you choose it to be. If you want to show off a classic crewneck, make certain to invest in one that is close-fitted, that perfectly contours your body. You can always wear a classic white tee look or bump your style up a notch and add some colors to the mix. 

V-Neck T-Shirts

V-necks are optimal if you want to leave a few buttons unbuttoned on your outer layer. Most V-neck t-shirts are constructed with a depth that allows you to leave at least one or two buttons undone when wearing a shirt over the top.

This style of undershirt serves a more practical purpose as it allows you to wear outer layers with a wider variety of necks. If you’re looking to show off your V-neck, make certain the cut fits close to your body, and the V is the right depth, and try to stick to more brightly-colored styles that will make a statement.

Long-Sleeve T-Shirts

If you live in colder climates, need that extra layer during the winter months, and don’t want to go the thermal underwear route, a long-sleeve undershirt is the way to go. 

Not only will they help absorb sweat and protect your shirts and sweaters from staining, but they also come in a wide range of colors so you can choose to layer your outfit or wear them on their own. 

If you choose the solo style, make certain the shirt flatters the contours of your body, and don’t be afraid to choose a bold color. They also look great when worn under a puffy vest, bomber jacket, or even with an unbuttoned flannel shirt.
